Creating Factions with WoWEmu

Does anybody know how to create new factions for WoWEmu?

I loaded the Factions.dbc into my DBC editor, but there are a lot of fields, I do not know what each one is for.

I also looked at FactionsTemplate.dbc, and still I am not 100% sure what all the fields do.

Like on column #3 for Stormwind it says "0000100000100001", and I have no clue what that means.

Edit: Also since were on the subject of DBCs, is it possible to create new sets? No matter what DBC editor I use, opening ItemSet.DBC always gives me a "file is corrupt, filesize is wrong." error.

Sorry, double post.

Dammit, pressed wrong button. Delete this post please.
